The Hebrew name"סרפד, serpad, maybe from סרף = שרף, "Seraf" שרף (resin) and it also indicates the burning characteristic of the plant.

There are four species of true nettles found in Israel: Urtica pilulifera, Urtica urens, Urtica membranacea (Urtica caudata, Urtica dubia), and Urtica kioviensis. They are all common pests of waste places and fields. In the Bible three different Hebrew names are quoted: Sirpad (סרפד)- in Isaiah 55:13; Seravim (סרבים)- in Ezekiel 2:6; Harul (הרול)-Zephaniah 2:9. They are synonyms, the roots s-r-f and h-a-r both meaning 'scorching' or 'burning'. Bible resources: Isaiah 55:13 Instead of the thornbush will grow the pine tree, and instead of briers the myrtle will grow. This will be for the LORD's renown, for an everlasting sign, which will not be destroyed. Ezekiel 2:6 And you, son of man, do not be afraid of them or their words. Do not be afraid, though briers and thorns are all around you and you live among scorpions. Hosea 9:6 Even if they escape from destruction, Egypt will gather them, and Memphis will bury them. Their treasures of silver will be taken over by briers, and thorns will overrun their tents. Zephaniah 2:9 Surely Moab will become like Sodom, the Ammonites like Gomorrah— a place of nettles and salt pits, a wasteland forever.
